CAR-COUPLING.

PECIFICATION forming part of Letters Patent No. 339,575, dated April 6, 1886.

Application filed January 1l, 1886. Serial No. 153,152. (No model.)

To @ZZ whom it may concern.-

Be it lruown that we, JOHN MYERS and SAMUEL L. MORRISON, of the city of Springiield, county of Clark, and State of Ohio, have invented certain new and useful Improvements inCar-Couplings, of which the following is a specification.

This invention relates to car-couplings, and is especially intended as au improvement upon that class of couplings known as automatic car-couplers.7

The objects of this invention are, in brief, first, to provide a car-coupling which shall be perfectly automatic in its operation, and to so construct the said coupling as to adapt it to couple with cars provided with the ordinary draw-head and link; second, to combine therein cheapness,siinplicity,and durability; third, obviate the use of springs; and, fourth, to provide mechanism to nncouple the cars to thereby obviate the necessity of train-hands going between cars, thus preventing accidents frequently resulting from such practice.

The invention consists in the combination, with a draw-head having a vertical longitudinal opening therethrough, of a lever pivoted at its rear end to the draw-head within the longitudinal opening, a. coupling-pin pivoted to the forward end of said lever and a tumblelatch or gravity-pawl pivoted at its upper end to the lever just in the rear of the couplingpin, all constructed and arranged substantially as hereinafter described.

It also consists in certain details ofconstruction of the several parts, as hereinafter fully explained.

Figure 1 represents in vertical longitudinal section a ear-coupling constructed in accordance with my invention, the pin being shown as elevated, the said ligure showing the draw-head as having two link-entering openings, and also showing in side elevation a smaller draw-head having but one link-entering opening,- Fig. 2, a plan view of the same; Fig. 3, a vertical longitudinal section of the saine, the pin being shown as lowered and the two draw-heads as coupled; Fig. 4, an enlarged sectional detail of the draw-head having a single link-entering opening, the two positions of the parts being designated one by full lines and the other by dotted lines.

The draw-head A, which in practice will l l i l preferably be constructed of cast metal, is in this invention very similar to the ordinary draw-heads now in use with ordinary freightcars, it differing only in that it has a vertical longitudinal opening, B, therethrough, as illustrated in the drawings, it having the usual link-entering openings, O, in its forward end.

ln the drawings one of the draw-heads A is shown as having two link-entering openings, (l. These openings are, however, merely provided as a convenience in coupling with cars of various heights, the links in some cars being higher from the track than others, and it will therefore be understood that this invention will not be limited to a draw-head having` two link-entering openings. u

Pivoted between thc walls of the opening B, at or near its rear end, is a gravity-lever, D, which lever is slightly curved upward at its forward end, as shown at c, the said lever being bifurcated at its extreme forward end, as at b, to 'forni ears,between which the couplingpin E is pivoted, said pin E being pivoted at or near its center to said lever D.

Pivoted to the lever D, just in the rear of the coupling-pin E, is a gravity-pawl or tumble-latch, F, said pawl being slotted centrally and longitudinally at its upper end to form ears c, between which ears the lever Dnioves, said gravity-pawl being pivoted at its extreme upper end slightly forward of its central gravity-line to the lever D.

Formed upon the draw-head A in a vertical line with the pivotal point of the gravitypawl F is a cross bar or lug, G, which lug has its upper face ou a horizontal plane with the lower wall of the link-entering opening C, and acts to support the pawl F when the pin E and lever D are elevated or in the position they occupy just prior to coupling.

We do not desire to limit ourselves to the exact shape or construction of the several elements constituting our invention, as these may be slightly modied, as the demand may require. The link E is of ordinary construction, and the pin E will in practice be pro- IOO vIO

pin may be elevated, and therefore we do not desire to limit ourselves to any special way or means for accomplishing this result. When the pin is elevated, and with it the lever D, the pawl F by its own gravitation moves forward and over the lug G,where -it is supported, and in turn supports the pin in an elevated position until pressed backward by the link which enters the opening C,when the pin deseends and enters the link. A stop or pin, H, is provided near the upper edge of the draw-head within the opening B, to stop the lever D from being elevated too high.

We claim- In a car-coupling, the combination, with the slotted draw-head A, having the lug H formed near its under face, of the gravity-leverD,

our hands and seals, at Springfield, Ohio, this 2d day 0f January, A. D. 1886.
